Description

Technical Field

[0001] This utility model relates to the field of polarizer processing technology, specifically to a polarizer lamination and coating equipment. Background Technology

[0002] Existing polarizer lamination equipment has low efficiency in connecting manual pre-lamination with mechanical lamination during operation. Some equipment requires complete manual lamination, which is labor-intensive and results in poor lamination uniformity. While some automated equipment can mechanically apply film, it is difficult to accurately match the initial positioning of manual pre-application, which can easily lead to film misalignment, air bubble residue, and other problems. Especially when dealing with scenarios where "one side is pre-applied manually first, and then mechanically assisted in bonding", the equipment's tracking and pressing accuracy of the pre-application position is insufficient, resulting in unstable bonding quality and affecting the yield of polarizer finished products. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a polarizer lamination and coating device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A polarizing film laminating device includes a worktable. A laminating assembly is provided at the upper end of the worktable. The laminating assembly includes a first slide groove. The first slide groove is provided on the left side of the upper end of the worktable, and a second slide groove is provided on the right side of the upper end of the worktable. A laminating plate is provided between the first slide groove and the second slide groove. A first rubber protective pad is provided at the upper end of the laminating plate. A first motor is provided at the rear end inside the second slide groove. A first threaded screw is provided at the transmission end of the front end of the first motor. A first movable ring is provided at the front end inside the second slide groove.

[0006] As a further improvement of this utility model: a first auxiliary ring is provided at both the front and rear ends of the first groove, a first guide rod is provided between the two first auxiliary rings, and a first guide slider is sleeved on the outer side of the first guide rod.

[0007] As a further embodiment of this utility model: a second motor is provided at the upper end of the second lifting box, a second threaded screw is provided at the transmission end of the lower end of the second motor, a second movable ring is provided at the bottom of the second lifting box, a second slider is sleeved on the outer side of the second threaded screw, an inverted U-shaped connecting frame is provided at the right end of the second slider, a second guide slider is provided at the right end of the inverted U-shaped connecting frame, a third movable ring is provided at both the left and right ends of the inverted U-shaped connecting frame, a rotating shaft is provided between the two third movable rings, a bonding film roller is sleeved on the outer side of the rotating shaft, and a second rubber protective pad is provided on the surface of the bonding film roller.

[0008] As a further improvement of this utility model: the upper and lower ends of the first lifting box are provided with second auxiliary rings, a second guide rod is provided between the two second auxiliary rings, and a second guide slider is sleeved on the outer side of the second guide rod.

[0009] As a further embodiment of this utility model: a support box is provided at the lower end of the workbench, a placement groove is provided inside the support box, and a placement box is provided inside the placement groove.

[0010] As a further embodiment of this utility model: a control panel is provided at the front end of the support box, a base is provided at the lower end of the support box, a support column is provided at the lower end of the base, and a rubber anti-slip pad is provided at the lower end of the support column.

[0011] Compared with the prior art, this utility model provides a polarizer lamination and bonding device, which has the following beneficial effects: 1. This polarizer laminating and bonding equipment uses a first motor to drive a first threaded screw to move the bonding component. It can accurately position the film material on one side that has been pre-applied manually, achieving a seamless connection between "pre-applied positioning and mechanical pressing", avoiding repeated manual adjustments and improving operational efficiency. 2. In this polarizer laminating and film-applying equipment, the second motor drives the second threaded screw to move the inverted U-shaped connecting frame and the laminating and film-applying roller up and down. The pressing force can be adaptively adjusted according to the thickness of the pre-applied film material. With the flexible contact of the second rubber protective pad, the polarizer is not damaged while ensuring that the pre-applied edge is tightly bonded to the polarizer, reducing the generation of air bubbles. 3. In this polarizer lamination equipment, when the lamination roller moves laterally with the first slider, it covers the unlaminated area by rolling and pressing. Compared with the traditional flat-press lamination, it can evenly distribute the lamination force and avoid wrinkles caused by uneven local force on the film material. It is especially suitable for the efficient lamination of large-area polarizers.

[0012] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

A connecting plate 210 is provided at the upper end of the first lifting box 209. A second lifting box 211 is provided at the lower left end of the connecting plate 210. A first guide slider 212 is provided at the lower end of the second lifting box 211. A first auxiliary ring 213 is provided at both the front and rear ends of the first slide groove 201. A first guide rod 214 is provided between the two first auxiliary rings 213. A first guide slider 212 is sleeved on the outer side of the first guide rod 214. A second motor 215 is provided at the upper end of the second lifting box 211. A second threaded screw 217 is provided at the transmission end of the lower end of the second motor 215. A second movable ring 216 is provided at the bottom of the second lifting box 211. A second slider 218 is fitted on the outer side of 7. An inverted U-shaped connecting frame 219 is provided at the right end of the second slider 218. A second guide slider 222 is provided at the right end of the inverted U-shaped connecting frame 219. A third movable ring 223 is provided at the left and right ends inside the inverted U-shaped connecting frame 219. A rotating shaft 224 is provided between the two third movable rings 223. A bonding roller 225 is fitted on the outer side of the rotating shaft 224. A second rubber protective pad 226 is provided on the surface of the bonding roller 225. A second motor 215 drives a second threaded screw 217 to move the inverted U-shaped connecting frame 219 and the bonding roller 225 up and down. The pressing force can be adaptively adjusted according to the thickness of the pre-applied film. With the flexible contact of the second rubber protective pad 226, the polarizer is not damaged while ensuring that the pre-applied edge is tightly bonded to the polarizer, reducing the generation of air bubbles.

[0019] like Figures 1-3As shown, the first lifting box 209 has second auxiliary rings 220 at its upper and lower ends, and a second guide rod 221 between the two second auxiliary rings 220. A second guide slider 222 is sleeved on the outside of the second guide rod 221. A support box 9 is provided at the lower end of the worktable 1. A placement slot 4 is provided inside the support box 9. A placement box 5 is provided inside the placement slot 4. A control panel 3 is provided at the front end of the support box 9. A base 6 is provided at the lower end of the support box 9. A support column 7 is provided at the lower end of the base 6. A rubber anti-slip pad 8 is provided at the lower end of the support column 7. By providing the rubber anti-slip pad 8, the device can be made more stable and have better anti-slip properties.

[0020] Working principle: The polarizer to be coated is placed on the first rubber protective pad 204 of the coating plate 203. The operator manually pre-coats the two front corners of the film to the edge of the polarizer to complete the initial fixation on one side. The first motor 205 is started through the control panel, which drives the first threaded screw 206 to rotate, causing the first slider 208 sleeved on the outside of the screw to move laterally in the second groove 202. Since the first slider 208 is fixedly connected to the first lifting box 209, the connecting plate 210, and the second lifting box 211, it pushes the entire coating frame (including the inverted U-shaped connecting frame 219 and the coating roller 225) to move above the manually pre-coated film, so that the coating roller 225 is aligned with the pre-coated edge. The second motor 215 is started, which drives the second threaded screw 217 to rotate, causing the second slider 218 to move downward along the screw. The two sliders 218 are fixedly connected to the inverted U-shaped connecting frame 219, which in turn pushes the bonding roller 225 downward to press it together. The second rubber protective pad 226 tightly presses the edge of the pre-applied film onto the polarizer, completing the initial fixation. At this time, the bonding roller 225 only contacts the pre-applied edge and does not cover the unapplied area. The second motor 215 is kept in the current pressing position, and the first motor 205 is started again to drive the first threaded screw 206, so that the first slider 208 drives the bonding roller 225 to move laterally towards the unapplied edge. During the movement, the bonding roller 225 rolls with the rotating shaft 224, pressing the film evenly onto the surface of the polarizer until the overall bonding is completed. During the rolling pressing, the first guide slider 212 slides along the first guide rod 214, and the second guide slider 222 slides along the second guide rod 221 to ensure smooth movement without deviation.
